...items in the Air Forces' announcement especially caught the eyes of airmen: 1) that the propellerless, kerosene-powered Shooting Star is in mass production (at four Lockheed plants and one operated by North American Aviation plants) and 2) that U.S. engineers have overcome the inordinate appetite of jet engines for eating up fuel. The P-80 has range enough to accompany bombers on all but the longest missions...
Since then hundreds of flights have been made, all without mishap, and some of the more seasoned necks of the Air Forces have been risked in the propellerless ships - among them those of 51 -year-old Lieut. General William E. Keprter, U.S. fighter commander in Britain; Brigadier General B. W. Chidlaw, 43, Materiel Division chief...
...pilots undoubtedly will be trained for them. Whether the development will move fast enough for them to play a part in this war no man can say. But for aviation in the future, jet propulsion undoubtedly has dazzling possibilities of speed, lightness and fuel economy. One problem a propellerless plane solves automatically is that of supersonic speeds at propeller tips; engineers have discovered that a propeller encounters "compressibility burble" and loses its effect on the air when the blade tips whirl at a speed approaching that of sound, about 750 m.p.h. at sea level...
...years ago had persuaded Chicago architects that he had vast financial backing, had inveigled them into drawing up preliminary plans for a $50,000,000 skyscraper, announced that he had invented: 1) a death ray, 2) a new bearing metal called "Oman" that requires no greasing, 3) a wingless, propellerless airplane that uses water for fuel, can fly 1,300 miles an hour. Inventor Ensign said he would complete his first plane next fall, fly around the world in a day. He then plans to make a more leisurely trip, dropping in on all the dictators to show them what...
